How to use AI to understand a confusing letter or bill

Updated October 17, 2026 · About 6 minutes to read · Free guide

A letter arrives from your insurance company. It's three pages long, full of codes and phrases like "allowed amount" and "patient responsibility," and somewhere in there it may or may not be asking you for money.

Most of us have sat at the kitchen table with a letter like that, reading it three times and feeling no wiser. This is one of the most useful everyday jobs for AI. It can turn official language into plain English in seconds.

Here's how to do it safely.

What AI is good at here (and what it isn't)

AI is good at:

Explaining what jargon means ("deductible," "coinsurance," "escrow").
Summarizing a long letter into a few short points.
Telling you what the letter seems to be asking you to do, and by when.
Helping you write a list of questions to ask, or a polite reply.

AI is not good at:

Knowing whether a charge is correct. It can't see your records.
Giving you legal or tax advice you can rely on.
Telling you for certain that a letter is genuine.

Use it to understand, then confirm the important parts with the company, your doctor's billing office, or a trusted person.

Step 1: Protect your private information first

Before you share anything, cover up the details that could be misused. This is the most important step.

Remove or hide:

Your name and address
Account numbers, policy numbers and member ID numbers
Your Social Security number and Medicare number
Your date of birth
Bank and card numbers

How to do it:

If you're typing or pasting the text: simply leave those parts out, or replace them with words like "[my name]" or "[account number]."
If you're taking a photo: place a sticky note or a strip of paper over the private details before you take the picture. Or take a photo of just the confusing paragraph.

The AI doesn't need your personal details to explain what a letter means.

Step 2: Get the words into ChatGPT or Gemini

You have two choices.

Option A: Type or paste the text. If the letter came by email or as a PDF on a website, you can copy the confusing part and paste it into the chat box. If it's on paper, type the confusing paragraph yourself. You don't have to type the whole thing.

Option B: Share a photo. Both ChatGPT and Gemini can read a photo of a document, including on the free versions (there may be a daily limit).

In the ChatGPT or Gemini app, look for a plus (+) sign, a paperclip, or a camera icon next to the typing box.
Choose Camera to take a picture, or Photos to pick one you've already taken.
Take a clear, well-lit picture with the page flat. Make sure your private details are covered.
Add your question in the typing box (see Step 3), then press send.

Step 3: Ask for a plain-English explanation

Copy this prompt and use it as is, or change the parts in brackets:

I'm not familiar with this kind of paperwork. Please explain this [letter / bill / statement] in plain English. Tell me: 1) who it's from and what it's about, 2) whether it is asking me to pay anything, and how much, 3) whether there is a deadline, and 4) anything I should do next. Keep it short and simple. Here it is: [paste text, or say "see the photo"]

Read the answer slowly. If anything is still confusing, just ask. For example:

"What does 'allowed amount' mean?"
"Explain the difference between the amount billed and the amount I owe."
"Is there anything in this letter I should be worried about?"
"Can you put the important parts in a short list I can print?"

Step 4: Check the answer against the letter

AI can misread a number, especially from a photo. So:

Look at the original for any amount, date or deadline the AI mentions. Make sure they match.
If the AI says "you owe $142," find $142 on the page yourself.
If something doesn't match, tell the AI: "The letter says $214, not $142. Please check again."

Step 5: Decide your next step, and confirm it

Once you understand the letter, you can decide what to do. AI can help with that too:

Based on this letter, help me write three short, polite questions to ask the billing office when I call.

Help me write a short, polite letter asking for an itemized bill.

Always confirm before paying. Call the company using the phone number on your card, your official statement, or their official website. Don't rely on a phone number from a letter you're not sure about.

Common letters AI can help with

"Explanation of Benefits" (EOB)

Your health insurance company sends these after a doctor visit. Many say right on them, "This is not a bill." It shows what the doctor charged, what insurance paid, and what you may owe. The actual bill, if there is one, usually comes separately from the doctor's office. AI can help you compare the two.

Medicare Summary Notice

If you have Original Medicare, you'll get a Medicare Summary Notice, usually every few months, listing services and what Medicare paid. It's also not a bill. AI can explain the columns and codes.

Medical bills

Ask the AI to explain each line. You can also ask, "What questions should I ask to make sure this bill is correct?" Billing mistakes happen, and it's always fair to ask for an itemized bill.

Utility and phone bills

Useful prompts: "Why might this bill be higher than last month?" or "What are these extra fees and taxes?"

Letters from government offices

AI can explain what a letter from the Social Security Administration or the IRS means. But be extra careful about scams. The IRS generally contacts people by mail first, and it won't demand payment by gift card or threaten immediate arrest by phone. If you're unsure, contact the agency using the number on its official website.

A word about scam letters

Some letters and emails are designed to look official. If a letter is pressuring you to pay quickly, asks for payment by gift card or wire transfer, or has a phone number you don't recognize, ask the AI:

Does this letter show any signs of being a scam? What should I check before I respond?

Then call the company directly using a number you already trust.

The short version

Hide your private details before sharing anything.
Paste the text or share a photo with ChatGPT or Gemini.
Ask for a plain-English summary: what it is, whether you owe money, any deadline, and what to do next.
Check numbers and dates against the original.
Confirm with the company before paying, using a phone number you trust.

The letter is no smarter than you. It's just written in a language you were never taught. Now you have a translator.
